Here's a Celtics scenario that uses Houston as the 3rd team:
BOS: Dwight Howard, Kyle Lowry, Hasheem Thabeet
ORL: Rajon Rondo, J. O'Neal, Glen Davis, 1st (Clippers), 1st (Houston)
HOU: Jeff Green, Jameer Nelson, 1st (Celtics)
Boston gets Superman, decent Rondo replacement (Lowry), Thabeet ("the stinker")
Orlando gets Rondo, Big Baby, an expiring deal, and 2 decent 1st rounders
Houston gets Green, Nelson for Lowry and Thabeet.
I think this is clearly a coup for Boston (getting Howard and still a good young PG), Houston gets two players for Lowry, and Orlando gets an affordable star, expiring deal, role player, and 2 decent 1st rounders.
